Find a hobie dealer and ask about buying the boxes the hulls come in, better yet, ask them how much to box up your 18. Freight would be for 3 individual packages. I would guess around 400-600 bucks. You might want to try UShip, you may find be able to find someone to piggyback it with another load. Sometimes they drive east to west and may not have a load to go back east, you may get a fairly cheap rate.
